f43234e1cb add prop:authentic and (struct .... #:authentic ....) 
An authentic structure type is one whose instances cannot be
impersonated or chaperoned. The intended use of `prop:authentic` is to
annotate a library-private data structure where impersonators are
never needed internally for the data structure, and the declaration
lets the compiler produce less code and fewer branches by omitting
impersonator support.

567679bf0a {impersonate,chaperone}-hash: add equal-key-proc wrapper 
The optional `equal-key-proc` wrapper effectively interposes on calls
to `equal?` and `equal-hash-code` for hash-table keys.

4354ce45d8 use `scribble/examples' for the Reference 
Port `examples`, `interactions`, etc., to use the new `examples`
form of `scribble/examples`. The main intended effect is to ensure
that errors are produced by examples only as specifically
indicated.

8e46e46d40 add more support for continuation marks in procedure impersonators 
Allow a more dynamic (than `impersonator-prop:application-mark`)
determination of continuation marks and associated values to wrap the
call of an impersonated procedure.

b923269569 make impersonator properties sensitive to prop:impersonator-of 
When a structure type has `prop:inpersonator-of`, follow it
when attemptng to access imperonator properties.

This change fixes a problem with `impersonate-procedure` as
reported by Scott Moore.

2d4f3e2ac9 remove the "racket-pkgs" directory layer 
The layer is now redundant, since everything left in "pkgs" is in the
"racket-pkgs" category.
